It is less important how many meetings you have and more the quality of the meetings.
The number of meetings you need to have depends on what you are trying to achieve by having them and how well they are executed.
Efficient meetings are consistent, organized and create accountability in your team. You should have your meeting at regular intervals, with an agenda that has been sent out ahead of time so everyone is prepared. Meeting minutes need to be recorded so that you have a history of decisions and who is responsible for action items.
By creating a recurring meeting rhythm with clear expectations about what will be discussed via the agenda, and a culture of accountability, you will require fewer meetings because your communication is consistent and structured. You also need to have fewer ad hoc meetings. This will help contribute to your overall success!
